Author and Anglican priest Lionel Fanthorpe returned to the show to share his research into the mysteries of Templar treasure and the Holy Grail. He named three possibilities as to what the Holy Grail might be: the sacred relic of Christ's cup from the Last Supper, an ancient magical artifact, or a reference to the actual bloodline of Mary Magdalene and Jesus, (Mary according to Fanthorpe was a descendent of King David). Legend has it that the offspring from this Christ bloodline eventually became the Merovingians that ruled France, he said.

The Templar Knights, who were involved in the mysteries and hidden treasures at Rennes-le-Chateau in France, may have been looking for ancient divination stones when they searched under Solomon's Temple back in 1118, he continued. The secretive Knights may have originated from a far older group-- "ancient guardians" who date back into the "dim parts of history," he noted.

Fanthorpe also theorized about the Ark of the Covenant, suggesting that Moses may have taken it from Egypt when they escaped, and that was possibly why they were so adamantly pursued by the Pharaoh because he was trying to get back what may have been a "great power source."
